Spoiler: It literally changes. LITERALLY.
Meditation is hardly a new topic of conversation. But, there's still plenty that remains unknown to most about the practice of training the mind, including the effect it can have on the brain.
While many people still associate meditation with the art of "thinking about nothing" it is actually the opposite, according to Dr. Craig Hassed, a senior lecturer at Monash Medical Faculty.
"All meditation practices involve training attention but also training the attitude of acceptance and non-reactivity, as well as attention on the breath and the body," Hassed tells BuzzFeed Life.
So, rather than thinking about nothing, real meditation practice is about properly acknowledging all of our thoughts, training our brain out of its default setting of letting life pass by.
And if you practice meditation regularly, researchers believe that it can have wonderful effects on your brain. Here's what might happen:

First, you should understand: Your brain can change and grow throughout your life.
This is called neuro-plasticity, and it's a relatively new buzzword in the field of neuroscience.
"The way that scientists used to think about the brain, until recent times, was that the brain wires itself in early development and early childhood, then after that, the only thing that happens to the brain is that it loses cells as we get older," Hassed says.
But recent research has poked big holes in that theory. Neuroscientists now know that you actually can teach an old brain new tricks.
"Today we know that our brains are changing all the time. Most changes take place on the micro-anatomical level and are very short-lived — so it is harder to measure them — but some changes even take place on the macro-anatomical level and can be captured by modern imaging technologies, such as MRI," Eileen Luders, Ph.D, Assistant Professor at UCLA School of Medicine Department of Neurology, tells BuzzFeed Life.

Some research shows that meditation is associated with a change to the amount of grey matter in the brain, which is a pretty big deal.
But, what even is grey matter — and why is it so impressive that it can change?
"When people talk about grey matter, they're talking about cells — the brain cells that connect to each other," Hassed says. "When a person learns a particular skill — like meditation — they're exercising those areas of grey matter, whose job it is to form that skill." Like you notice muscle gain after physical exercise, research shows that meditation may stimulate the growth of new brain cells — which means more measurable grey matter in certain areas of the brain.
Beyond reported differences in grey matter between meditators and people who don't practice, meditation has also been associated with a slowdown in the natural loss of grey matter, which occurs with aging. "In our latest study, we extended our focus of research by looking at the potential impact of aging on the brain, specifically the impact of aging on the brain's grey matter. Again, our analysis revealed a striking difference between meditators and controls: meditators' brains seem to be much less affected by the normal, natural age-related gray matter decline," Luders says.
What this means: People who meditate regularly may slow down their brain's aging process. Go meditation!

Meditation has also been linked to changes in the hippocampus, the part of the brain responsible for forming memories and spatial awareness.
A 2011 study compared the brains of people who meditated for about 40 minutes each day with the brains of demographically-matched people who didn't meditate at all.
Brain scans revealed that there were some areas of the meditator's brains with more grey matter — and one of these areas was the hippocampus.
